Experimental and simulation method of introducing compressive residual stress in ASTM A516 grade 70 steel
Compressive residual stress below the surface of material could increase fatigue life as it encounters the tensile loading applied on the material during operation. Shot peening process is a common surface treatment to introduce this stress. This study will investigate on how to introduce the same a...
